JOHN M. RUTLEDGE, OF MID'VALE, OHIO.

IPIPE AND ROD WRENCH.

Application filed May 5, 1914.

To all whom it may concern Be it known that l, JOHN M. RUTLEDGE, citizenof the United States, residing at Midvale, in the county of Tuscarawasand State of Ohio, have invented certain new and useful Improvements inPipe and Rod Wrenches, of which the following is a specification.

This invention relates to improvements in pipe and rod wrenches, and hasfor one of its objects to provide a simply constructed device which isreadily applicable to pipes and rods of varying sizes, and which willfirmly grip the same and prevent it from rotation thereon.

Another object of the invention is to provide a simply constructeddevice which may be applied to rods or pipes of varying sizes and whichmay be applied to the rod or pipe at otherwise inaccessible locations.

W'ith these and other objects in view the invention consists in certainnovel features of construction as hereinafter shown and clescribed andthen specifically pointed out in the claims; and in the drawingsillustrative of the preferred embodiment of the invention Figure 1 is aside elevation of the improved implement applied to a section of a pipe.Fig. 2 is a front elevation of the parts shown in Fig. 1.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved device comprises a stock or handle 10 preferably tubular,and formed with spaced cheek portions 1112 at one end. The stock ispreferably constructed from a section of piping, the cheek portions11-12 being formed integral therewith as represented.

Pivoted at 13 between the cheek portions 1112 is a head member 14, thehead member being considerably less in thickness than the distancebetween the cheek members 1112 and held centrally between the same byspacer members 15. In its outer edge the head member 14 is formed with aconcaved recess having gripping teeth 16 as shown. One edge of themember 14 is formed eccentric to the pivot 13 and the eccentric edgeprovided with ratchet teeth 17. Pivoted at 18-19 to the cheek members1112 and between the cheek members and the head member 14 are arms 2021.The arms 20-21 are coupled near Specification of Letters Patent.

their outer ends by a pin 22 which thus holds the arms in spacedrelation. At their outer ends the arms 2021 are provided with outwardlyopening hooks 2321. The arms 20Q1 are thus free to swing upon theirpivots 1S19 and operate in close proximity to the side faces of themember 1 A flexible member 25 is formed of a plurality of linkspivotally united at 26. the pivot 26 of the innermost link beingutilized to unite one end of the flexible member to the head 14: asshown. The links of the flexible member 25 are arranged to pass betweenthe outer ends of the arms 2021, and the pivots 26 of the links areextended at their ends to engagein the hooks 232 Any required number ofthe links may be employed, and each link is adapted to be coupled by thepivots 26 with the arms 2091 as represented in Figs. 1 and 2. By thismeans the improi'ed wrench may be adapted to fit rods or pipes ofvarious sizes by simply adjusting the flexible member 25 relative to thearms 2021, as hereafter more fully explained.

is extended into the interior of the stock 10 as represented at 29, andformed with an outwardly directed terminal 30 which extends through anopening in the stock 10. A spring 31 is arranged to maintain the bill ofthe pawl 28 yieldably in engagement with the ratchet teeth 17, but willyield when pressure is applied to the terminal 30 to force the pawl fromengagement with the ratchet teeth. The stock 10 is preferably providedwith a hollow or recess 32 where the aperture for the terminal 80 islocated, so that the movement of the pawl may be increased withoutincreasing the size of the stock 10, and likewise preventing undueprominence to the member 30.

The parts are all constructed of metal, preferably steel with the member14 and its teeth 16 hardened to withstand the strain to wh ch they willbe subjected.

\Vith a device thus constructed. it will be obvious. that by releasingthe flexible member 2526 from the arms 2021 and actuating the pawl Q8-29to release the head 14 and moving the latter upon its pivot 13 until thepawl is in engagement with the ratchet tooth 17 which is nearest to theconcaved toothed edge 16, the improved device may be applied to a rod orpipe by placing the gripping edge 16 of the member 14 against the pipeor rod at one side and then passing the flexible member 2526 around thepipe and drawing it as closely as possible and engaging the nearest pin26 with the hooks 28-424. Then, by moving the stock 10 in a direction tocause the pawl 28 to pass over the inclined sides of the ratchet teeth17 the head 14: will firmly grip the rod or pipe and effectually lockthe wrench device to the rod and prevent it from rotating thereon, thusenabling the rod or pipe to be rotated by actuating the wrench.

The improved device is simple in con-- struction, can be strongly andinexpensively constructed and in varying sizes to suit rods and clampsof correspondingly varying sizes.

Having thus described the invention, what is claimed as new is:

1. A wrench comprising a stock, a head member mounted to swing in saidstock and having one edge eccentric to its pivot and another edgeconcaved and provided with gripping teeth, a flexible member swinging atone end from said head, means for adjustably connecting said flexiblemember relative to said stock, and means for holding said swinging headin any adjusted position.

2. A wrench comprising a stock, a head member mounted to swing in saidstock and having one edge eccentric to its pivot and provided withratchet teeth and another edge concaved and provided with grippingteeth, a flexible member swinging at one end from said head means foradjustably connecting said flexible member relative to said stock, and amanually actuated pawl engaging said ratchet teeth.

3. A wrench comprising a stock, a head member mounted to swing in saidstock and having one edge eccentric to its pivot and another edgeconcaved and provided with gripping teeth, a flexible member swinging atone end from said head member, an arm swinging from said stock, andmeans for adjustably connecting said flexible member to said arm, andmeans for holding said swinging head in any adjusted position.

4-. In a wrench of the class described, a stock having cheek membersspaced apart, a head member pivoted between said check members andhaving gripping teeth in one edge, an arm pivoted in said stock, aflexible member adapted to be adjustably and detachably engaged in saidarm, and means for holding said swinging head in any adjusted position.

In testimony whereof I afiix my signature in presence of two witnesses.
